Due to the good weather we're having down in sunny Southend at the moment I've managed to have the sunroof open lots 
I'm not sure wheter it's in my head but i've noticed a slight decline in acceleration when the roof is open! Does anyone know how much an open sky roof declines the aerodynamic efficiency? If it affects acceleration to a noticeable degree it must be terrible for mpg! Anyone got any figures?
Thanks,
Edd.
